I remembered this from a similar thread last year, and whilst probably a little out of date now and in need of a refresh, this should get you started:
https://www.google.co.uk/maps/@51.9128931,0.7126326,7z/data=!4m2!6m1!1szTVdLZ2LNGeE.k5LHoM85eG3I?hl=en
Just as a note, I didn't make this so am not taking credit in anyway, I just remember it getting posted a while ago and I have kept it saved since then. I'm sure between us on here it could be kept up to date by a select few volunteers, then be kept as a reference on the forum for everyone to see and / or update as sites change etc.
Maybe if I get time I might get the ball rolling with a few updates, if possible, although I haven't travelled to that many further away yet, so would only be able to go on information found online and would need a bit of help from others to verify if the details on the map are still correct.
